Case in point: Validation is just a tool, not a measuring stick. I use CSS3 in my designs and you should see the "this doesn't exist!" errors it pushes in my direction to make it cross compatible. I do wish that the W3C would default to CSS3 though, it's not like it's going to lose CSS 2.1 support with the upgrade. :lol:

got it. the scroll is looking consistent in all major browsers so whatever

Just so you know, it will look the same in just about every browser (I'd bet that about 99% of the market today has a browser that supports overflow-x/y, it's just that it's CSS3 and since that isn't a standard and recognized by the validator (this doesn't mean don't use it!) then it won't validate.
